'ro VALL WHOM ITMA'Y commits:V

Be it known that I, v(IL-*Hl ECCLESTON, of Oxford, in the county of Ghenango, in the State of New York, have invented Au. new und useful Improvement in Locped Ins for Securing Articial Teeth to agum or metal plete; end I do hereby declare the following to be a full and exact description thereof, reference being had t'o4 the accompanying drawings, forming a, part of this-specification. v e

- The nature of my invention consists in forming a. flathead upon the loop of the `pin, in projecting the Shanks therefrom ate right angle thereto, 'and in bending the ends of said shanks tohold them in the bodyoi the tooth;

In the accompsnyingdrslwings, E (see IFigure 3) represents the head, constituting the'loop of the-pin, This hond is mndeiiat, and lcomparatively broad, so as to give firm hold to the vulcanized gum or to the metalconstituting the plate for the teeth. From this head or loop, at either end thereof, .nud at right anglestheteto, projectthe Shanks g, (see Figure 2,) which are inserted in the body of the tooth, to connect and hold the seineI to ,itsplete By thus combining the shanks t'o the head-'ofthe loop, theelarges't possible open space is obtained within the loop, whilst the dat form. of the heed ifords the iirmest'hold .for-the gum or metl of the-plate, with the least proportionate displacement thereof'e In order to secure properly the shunks in the body of the tooth, I bend the ends of said s hanks at njright angle'therewith, es shown nt F, in Figure 1 of the drawings,.thus avoiding the costof a round or flattened head on each point, .and yet obtaining n.` secure fastening thereof, so thatthey cannot bevwithdrcivn 'when once embeddedin the tooth.

IV do notclniln n. double-headed:rivetjfor `insertion in the teeth, nor'yet n loop to project from the teeth, when said loop iscurved or imilde without enlargement of the looped portion thereof; but, having fully described my improvement, r

I claim as new, and desire to secure by Letters'Pntent'- 4 An angular loopV for securing urtiiicislV teeth, when made with an enlarged and flattened head, provided with projecting Shanks vy'hose outer ends are bentat an angle therewith, all substantially in the msnneil herein set forth. i
